My girlfriend and I have been seeing each other exclusively for 4 months (we dated for a few weeks before) In the beginning we spent a lot of time together, nearly every evening for about a month. Then we started having sex several times a week. Several weeks after, she decided that we should take a break from sex to get to know each other better before continueing. It has now been 2 1/2 months since then and we have not had sex again, nor is the relationship really progressing during this time. She has started making less and less time for me and has been acting really hot and cold, calling me and excitedly asking me to come see her one night and then being conveniently busy,tired,or sick for a day or two and then when we do spend time together after the “cold spell” she seems far less affectionate and distracted. Then back to affectionate and “i miss you, come see me” It’s not like its a big deal for me to come see her she lives 10 minutes away. Its like a rollercoaster. This doesn’t bother me nearly as much as the fact that her sons father comes over sometimes in the evening and stays 1-2 hours past when their son should be asleep. I’ve expressed my concern about the ex/babys daddy and she reassures me that she is not interested in him at all and only allows him over to spend time with his son. It just seems fishy to me when i add up all the facts. She tells me she loves me but I’m not sure what to make of it.
