Anyone married or dating a pipeliner? Advice please!

This maybe unrelated to some of these posts, but I need advice! Please! Please don’t give me any backlash! Does anyone date a pipe liner? I have no one to confide in. My boyfriend is a welder on the pipeline and is gone for weeks or months at a time. It’s hard! Well he recently has come home for 2 months. He and I live in two different states, but only 4 hours apart. He only has his camper, no home. He came and stayed here about 2 1/2 weeks to spend time with me and my children and then left. He will be off for a wihile longer. He’s now gone back to Texas. He came here one afternoon this week and left the next morning. I promise I know he definitely needs time with his friends and what family he does have there. I get that and I accept that. It’s like I’ve now been put on the back burner. When he’s there he usually just goes to his buddies and hangs out. I guess I am just really hurt considering I want to be with him 24/7. I don’t see him everyday all year like most wives. He always claims he has things to do, but always just ends up hanging out. Please tell me if I am over reacting. I could understand a few weekends going home and spending time there. We are in a very “serious” relationship. Now I just feel lonely knowing he is able to be here, but isn’t and will be back at work sooner than later. I have two children so I can’t just up and go at anytime. Any advice is welcome to help me through this. We have talked about getting a house and marriage, but that’s all been silent lately. I know he loves me, but I am just so confused and don’t want to be selfish. I pray someone can at least give me a answer I am looking for! I just feel unloved and irrelevant. I just don’t want to confront it and make him feel obligated. He also has no children. Has anyone else experienced this? I just don’t want to ask to much of someone and look stupid! So it keeps telling me the content is too short lol so I really have nothing else to add to that! Thank y’all!
